Abstract

The utility model discloses a device with permanent magnet for separating magnetic substances from materials. An outer rolling cylinder without magnetism is arranged in a body and is driven by a stepless speed change device. An inner cylinder is positioned in the outer rolling cylinder. The part of the inner cylinder on a discharge port is provided with an involute-shaped cross section. The magnetic system of the inner cylinder adopts a mixed magnetic circuit design and the magnetic system has same polarity in an axial direction. The rolling cylinder rolls by N and S alternately. The inner cylinder is driven to swing by a speed reducer through a rocking equipment to separate magnetic substances from non-magnetic substances. Because magnetic substances on the surface of the rolling cylinder are open and rolling when materials pass through a magnetic field, magnetic blocks and magnetic linkage can be formed. The device is suitable for separating magnetic substances from fine materials.

Description

Dry extraction magnetic dressing machine for fine material

The utility model relates to a kind of permanent magnet separation, particularly a kind of device that can sub-elect magnetisable material in the superfine material.

Usually the material concentration equipment that adopts is the drum-type concentration equipment, its inner core adopts permanent magnetic system, the alternating polarity of inner core magnetic pole is arranged, during sorting material, outer cylinder rotates, because magnetisable material easily forms by ferromagnetic material after entering magnetic field in the superfine material, intergrowth and be wrapped in the middle of the magnetic linkage that namagnetic substance constituted, if cylinder is done rotation at a slow speed, separate with ferromagnetic material than the namagnetic substance in the difficult removing magnetic linkage with intergrowth, even reduce the magnetic field intensity of concentration equipment, still be difficult to magnetic linkage is destroyed, if cylinder is made quick rotation, when producing rotating excitation field, though magnetic linkage can destroy, but because under action of centrifugal force, part magnetisable material will be dished out simultaneously with namagnetic substance, make after the sorting that magnetic material content is still higher in the material, do not reach the regulation requirement, so this device only can be used for the magnetisable material in the following material of sorting 240 orders, at present still adopt acid wash to handle ferromagnetic material in the superfine material for the superfine material more than 240 orders, adopting acid wash to handle is to use contained ferromagnetic material in the sulfuric acid corrosion superfine material in acidproof pond, again material is carried out neutralisation treatment after the pickling.This method not only floor space is big, the processing cost height, and the waste water that is discharged has pollution to environment, and labour intensity is also bigger.

The purpose of this utility model be to provide a kind of can the sorting superfine material in the device of magnetisable material, not only floor space is little for it, processing cost is low, labour intensity is little, and sharpness of separation is higher.

The utility model is to realize like this, the outer cylinder of no magnetic is positioned at internal body and is bearing on the body by bearing, and by the stepless speed changer driving, make its rotation, the permanent magnetism inner core is positioned at outer cylinder inside, inner core magnetic system adopts rare earth permanent-magnetic material and the design of ferrite permanent-magnet materials mixed magnetic circuit, be homopolarity axially in the magnetic system, the rollers roll direction is pressed N, S is arranged alternately on the inner core cylinder, the inner core cross section that is positioned at the discharging opening position is the involute shape, and the suffered magnetic force of magnetisable material is easy to a little less than more and more separate when making separation of material, and reductor is positioned at body one side, and be connected with inner core by rocking equipment, can drive inner core by rocking equipment and swing back and forth.Feed arrangement is positioned at the top of body, can make the outer drum shaft in material edge to even distribution during charging.Left side along drum shaft, the underpart of right position is provided with two discharging openings, during material handling, outer cylinder is under the drive of stepless speed changer, make its rotation, reductor drives inner core by rocking equipment and does oscillating motion simultaneously, when sorted materials is passed through magnetic field, magnetisable material in the material is folding rollover states simultaneously at cylinder surface, make the magnetisable material in the superfine material can't form magnetic group and magnetic linkage, the magnetic force that is changing, under the effect of gravity and mechanical force, magnetisable material can produce different movement locus with namagnetic substance, by two discharging openings magnetisable material is separated with namagnetic substance, thereby realization sub-elects the purpose of magnetisable material in the superfine material.

In conjunction with the accompanying drawings the utility model is elaborated below by embodiment:
